IPC: H01M8/02
Filed: 2001-06-15
Abstract: PROBLEM TO BE SOLVED: To produce desired electric power and reduce size by effectively, using supply regions of fuel gas and oxidizing gas. SOLUTION: Separators 36 are formed and catalyst electrodes 32 and 33 are applied to opposite surfaces of an electrolyte membrane 31, in order that gas supply regions to which the separators 36 effectively supply fuel gas and oxidizing gas are inside the application regions of the catalyst electrodes 32 and 33 on the opposite surfaces of the electrolyte membrane 31, even under a manufacturing error and an assembly error. Generation of an electrochemical reaction in all regions of the gas supply regions can produce desired electric power from a fuel cell 20. Since electrochemical reaction can be generated in all regions of the gas supply regions, even under a manufacturing error and an assembly error, the separators 36 can be dimensionally reduced, and the fuel cell 20 can be made compact in size.

Title: Method of manufacturing compound semiconductor device
Inventor: ASANO TETSUO
IPC: H01L21/60
Filed: 2001-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a compound semiconductor device especially using a GaAs substrate which eliminates the drawback that a silicon nitride film is apt to break at bonding because of the hardness of a substrate and the film by removing the silicon nitride film formed beneath pad electrodes until the final step for safety.
